Out of memory error in VB

Hi I'm working on an SMS project. I have a problem that is I keep getting run-time error 7 which is says out of memory. When I go into debug mode it brings me to the line
strBuffer = StrConv(MSComm2.Input, vbUnicode). It occurs only occasionally and I have no idea why. I did clear strBuffer before I used it again. Funny thing is that I used this statement at many other places in my code but always seem to obtain the error at only a particular usage of it. Part of my code is:-

strBuffer = ""
Trace ("Reading message...")
MSComm2.Output = "AT+CMGR =" & msgIndex & vbCrLf

Sleep 500

strBuffer = StrConv(MSComm2.Input, vbUnicode)
Trace (strBuffer)

I reused this chunk of code at many areas of the code, only replacing the AT commands by other AT commands. Please help me solve the out of memory error. Thanks.

try this:
recreate the whole project in a new folder with add the forms and other modules whatever you've created for this project to new folder. save the project and compile again. and see if that problem come back.

Hmm...nope it doesn't work...

This problem occurs generally coz of corrupted .vbp file.

try this maybe it helps:

i do not have a reference to fm20.dll in the first place...

Is "strBuffer" big enough to hold the message ?

I believe so...this is my code which I have the out of memory problem with...thanks...

You said the error occurs only occasionally.
Do you know which messages were being read when the error occurred ?
Can the same message be read without error ?

Does it help to make the sleep delay longer ?

yes it does seem to help...thanks a lot...
